Heat dissipating assembly for head-mounted displays

1. A head-mounted display (HMD) comprising: a face plate, and a main body configured to attach the face plate to cover a front portion of the main body, the main body comprising: a front plate comprising a plurality of first air channels defined by a set of ribs formed at a rear side of the front plate facing away from the face plate, at least a subset of the plurality of first air channels extending vertically to convey air from a bottom portion of the main body to an upper portion of the main body, a back plate attached to the front plate and located further away from the face plate than the front plate, and a circuit board between the front plate and the back plate.

2. The HMD of claim 1 , wherein the front plate further comprises at least one heat pipe at a front side of the front plate, the at least one heat pipe traversing one or more of the plurality of first air channels to improve thermal dissipation.

3. The HMD of claim 2 , wherein the back plate comprises a plurality of second air channels for conveying air from the bottom portion of the main body to the upper portion of the main body, wherein at least a subset of the plurality of second air channels extending vertically is conjoined with the subset of first air channels extending vertically.

4. The HMD of claim 2 , wherein the at least one heat pipe comprises a first heat plate and a second heat plate thermally coupled to the first heat plate, and wherein the first heat plate is horse shoe shaped.

5. The HMD of claim 1 , wherein an air gap is formed across a periphery of the face plate and an inner wall of the main body to intake air between the front plate and the back plate and discharge air passing through the front plate and the back plate.

6. The HMD of claim 1 , wherein the front plate comprises heat conductor columns extending vertically to enhance heat transfer to air passing through the at least one first channel.

7. The HMD of claim 1 , wherein each of the front plates are formed with windows for receiving an intake air or discharging an outflow air.

8. A main body of a head-mounted display (HMD), the main body comprising: a front plate comprising a plurality of first air channels defined by a set of ribs formed at a rear side of the front plate, at least a subset of the plurality of first air channels extending vertically to convey air from a bottom portion of the main body to an upper portion of the main body, a back plate attached to the front plate and located behind the front plate, and a circuit board between the front plate and the back plate.

9. The main body of claim 8 , wherein the front plate further comprises at least one heat pipe at a front side of the front plate, the at least one heat pipe traversing one or more of the plurality of first air channels to improve thermal dissipation.

10. The main body of claim 9 , wherein the back plate comprises a plurality of second air channels for conveying air from the bottom portion of the main body to the upper portion of the main body, wherein at least a subset of the plurality of second air channels extending vertically is conjoined with the subset of first air channels extending vertically.

11. The main body of claim 9 , wherein the at least one heat pipe comprises a first heat plate and a second heat plate thermally coupled to the first heat plate, and wherein the first heat plate is horse shoe shaped.

12. The main body of claim 8 , wherein an air gap is formed across a periphery of a face plate in front of the main body and an inner wall of the main body to intake air between the front plate and the back plate and discharge air passing through the front plate and the back plate.

13. The main body of claim 8 , wherein the front plate comprises heat conductor columns extending vertically to enhance heat transfer to air passing through the at least one first channel.
